Abstract

A display comprises: a video presenting means (10) receiving presentation style data describing a plurality of monomedia data and the presentation style of the frame of each monomedia data, generating scaling/synthesis control information (111) for synthesizing respective monomedia data, and generating a synthesis video frame (103) by synthesizing respective monomedia data; a video quality enhancing means (20) for determining the correction object area of specified monomedia data in the synthesis video frame (103) according to the scaling/synthesis control information (111), generating correction data by determining the inter-frame difference in the correction object area, and generating a display video frame (104) by enhancing the video quality of the correction object area with the generated correction data; and a video display means (30) for displaying the display video frame (104).
